Credit to OP--I just put all three parts into one post. That being said, someone make a fanfiction of this!<<<Love this, but Cedric was kinda sorta the only well known hufflepuff in the books and movies, till Newt, also rinks though not as well known.
This is why these people are so amazing. :) Not only did Lauren improvise that, but Joe reacted perfectly to the point that everyone thought they had planned it! My favorite scene in any of the potter musicals.
